Delineating the Mechanism of Ionic Liquids in the Synthesis of Quinazoline-2,4(1H,3H)-dione from 2-Aminobenzonitrile and CO2

Paul Joseph Dyson, Gabor Laurenczy, Martin Hulla, Shoubhik Das, Sami Manoubi Armand Chamam

Ionic liquids (ILs) are versatile solvents and catalysts for the synthesis of quinazoline-2,4-dione from 2-aminobenzonitrile and CO2. However, the role of the IL in this reaction is poorly understood. Consequently, we investigated this reaction and showed ...

Increasing the Sensitivity to Short-Lived Species in a Modulated Excitation Experiment

Davide Ferri, Oliver Kröcher, Alexander Wokaun

The combination of spectroscopic and diffraction methods to study chemical transformations is fundamental for the understanding of reaction mechanisms. The identification of short-lived species, likely active species, is often hindered by the contribution ...

trans-Mutation at Gold(III): A Mechanistic Study of a Catalytic Acetylene Functionalization via a Double Insertion Pathway

Gabor Laurenczy

The Au(III) complex Au(tpy)(OAcF)2 (OAcF = OCOCF3; tpy = 2-(p-tolyl)pyridine) catalyzes the anti addition of trifluoroacetic acid (HOAcF) to acetylene to furnish vinyl trifluor- oacetate. The Au(III) vinyl complex Au(tpy)(OAcF)(CHCHOAcF) (vinyl group bond ...

Water-assisted oxygen activation during gold-catalyzed formic acid decomposition under SCR-relevant conditions

Davide Ferri, Oliver Kröcher

Owing to the problems associated with the use of urea as an ammonia precursor compound in the selective catalytic reduction process in automobiles, alternative compounds such as ammonium formate, methanamide, and guanidinium formate have been suggested as ...

Exploring chemodiversity in metabolism towards the selective integration of chemistry into biology

Vassily Hatzimanikatis, Jasmin Maria Hafner, Noushin Hadadi

The availability of different levels of omics data helps us to observe cells with higher resolution and from different perspectives. Consequently, the computational exploration of metabolism gained more importance in the last decade to make sense of newly ...

Interactions of TiO2 nanoparticles and the freshwater nematode Plectus aquatilis: particle properties, kinetic parameters and bioconcentration factors

Kristin Schirmer, Julita Maria Stadnicka-Michalak, Laura Sigg

Principles for determining uptake kinetics and bioconcentration factors for nanoparticles and test organisms have only been cursorily explored. Here we report the derivation of bioconcentration factors (BCFs) and the role of surface functionalization in th ...

Room temperature decarboxylative cyanation of carboxylic acids using photoredox catalysis and cyanobenziodoxolones: a divergent mechanism compared to alkynylation

Jérôme Waser, Matthew Wodrich, Franck Le Vaillant

The one-step conversion of aliphatic carboxylic acids to the corresponding nitriles has been accomplished via the merger of visible light mediated photoredox and cyanobenziodoxolones (CBX) reagents. The reaction proceeded in high yields with natural and no ...

Reliable Performance Characterization of Mediated Photocatalytic Water-Splitting Half Reactions

Sophia Haussener, Meng Lin, Lihao Han

Photocatalytic approaches using two sets of semiconductor particles and a pair of redox shuttle mediators are considered as a safe and economic solution for solar water splitting. Here, we report on accurate experimental characterization techniques for pho ...

Room temperature C(sp(2))-H oxidative chlorination via photoredox catalysis

Xile Hu, Lei Zhang

Photoredox catalysis has been developed to achieve oxidative C-H chlorination of aromatic compounds using NaCl as the chlorine source and Na2S2O8 as the oxidant. The reactions occur at room temperature and exhibit exclusive selectivity for C(sp(2))-H bonds ...
